| 12 | help |
| 13 | Say Y or M here if you want to enable BIOS Enhanced Disk Drive |
| 14 | Services real mode BIOS calls to determine which disk |
| 15 | BIOS tries boot from. This information is then exported via sysfs. |
| 16 | |
| 17 | This option is experimental and is known to fail to boot on some |
| 18 | obscure configurations. Most disk controller BIOS vendors do |
| 19 | not yet implement this feature. |

| 25 | help |
| 26 | If you say Y here, you are able to get EFI (Extensible Firmware |
| 27 | Interface) variable information via sysfs. You may read, |
| 28 | write, create, and destroy EFI variables through this interface. |
| 29 | |
| 30 | Note that using this driver in concert with efibootmgr requires |
| 31 | at least test release version 0.5.0-test3 or later, which is |
| 32 | available from Matt Domsch's website located at: |
| 33 | <http://linux.dell.com/efibootmgr/testing/efibootmgr-0.5.0-test3.tar.gz> |

| 39 | bool "Console device selection via EFI PCDP or HCDP table" |
| 40 | depends on ACPI && EFI && IA64 |
| 41 | default y if IA64 |
| 42 | help |
| 43 | If your firmware supplies the PCDP table, and you want to |
| 44 | automatically use the primary console device it describes |
| 45 | as the Linux console, say Y here. |
| 46 | |
| 47 | If your firmware supplies the HCDP table, and you want to |
| 48 | use the first serial port it describes as the Linux console, |
| 49 | say Y here. If your EFI ConOut path contains only a UART |
| 50 | device, it will become the console automatically. Otherwise, |
| 51 | you must specify the "console=hcdp" kernel boot argument. |
| 52 | |
| 53 | Neither the PCDP nor the HCDP affects naming of serial devices, |
| 54 | so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending |
| 55 | on how the driver discovers devices. |
| 56 | |
| 57 | You must also enable the appropriate drivers (serial, VGA, etc.) |

| 66 | DELL system. Note you need a Dell OpenManage or Dell Update package (DUP) |
| 67 | supporting application to comunicate with the BIOS regarding the new |
| 68 | image for the image update to take effect. |
